What has happened in Florida?

In the race for Florida's Senate seat, unofficial results revealed a gap of just 0.15% between the votes for incumbent Democrat Bill Nelson and Mr Scott.

Democrat Andrew Gillum had already conceded the state governorship, but Ron DeSantis's lead for the Republicans later narrowed to 0.41%.

After the recount was announced, Mr Gillum said: "I am replacing my words of concession with an uncompromised and unapologetic call that we count every single vote."

Mr DeSantis, however, insisted that the results were "clear and unambiguous, just as they were on election night".

"It is important that everyone involved in the election process strictly adhere to the rule of law which is the foundation for our nation," he added.

Mr Trump had earlier said there was "a lot of dishonesty" over contested votes.

Some candidates have already launched legal action. Mr Scott, who claimed victory on Tuesday, is suing officials over an election recount, while Mr Nelson is suing over uncounted ballots - and there have also been a number of protests outside the elections office.

Mr Scott called on sheriffs in every county to closely monitor the recount process, tweeting: "We will not let unethical liberals steal this election!

"It's time Senator Nelson accepts these results and allows the state of Florida to move forward to a better future."

In one of his three lawsuits against election overseers, Mr Scott has asked a judge to impound voting machines and ballots when they are not in use.

Mr Nelson responded to the legal action in a statement on Sunday, saying his rival, the state's outgoing governor, was making "false and panicked" voter fraud claims because he was afraid of losing.

"If Rick Scott wanted to make sure every legal ballot is counted, he would not be suing to try and stop voters from having their legal ballot counted as intended," said the Democratic incumbent.

Authorities have meanwhile shot down a conspiracy theory about ballot fraud.

Florida Senator Marco Rubio was among those who retweeted a photo showing a box labelled "provisional ballots" found at a school, raising concerns about possible foul play.

Maybe this box found this morning has office supplies in it. But if it contains just a single vote, it should have been handled in accordance with the law, NO MATTER WHO IT WAS A VOTE FOR. pic.twitter.com/lfZ2Up6UDW

As soon as Democrats sent their best Election stealing lawyer, Marc Elias, to Broward County they miraculously started finding Democrat votes. Don’t worry, Florida - I am sending much better lawyers to expose the FRAUD!
